Traffic Light Simulation

Traffic Light Simulation

• Lynn Jepsen

Introduction and Background

• Try and find the most efficient way to move cars
  through an intersection given different traffic
  densities
• Currently have a simulation that obeys most
  rules of the road but no light algorithm
• Want to see waiting time for cars go down
• Many traffic simulations out there, but none that
  I have seen with a learning light

Development

• Cars on each lane take up a certain number of
  spaces and have a certain speed at each instant
• Speed and space is update every .1 sec along with
  graphics
• Speed up when object in front is getting farther
  away but with a max. accel.
• Slow down for red and most yellow lights
• Yellow lights don't always look right
• Use Java to show graphics
• Eventually show graphs of waiting time
• Need to give artificial intelligence to light

Results and Conclusions

• The simulation looks realistic
• Shows how easily heavy traffic flow can back up
  if the light has no algorithm
